IllegalArgumentException: navigation destination xxx is unknown to this NavController

In my case, if the user clicks the same view twice very very quickly, this crash will occur. So you need to implement some sort of logic to prevent multiple quick clicks… Which is very annoying, but it appears to be necessary.

You can read up more on preventing this here: Android Preventing Double Click On A Button

Edit 3/19/2019: Just to clarify a bit further, this crash is not exclusively reproducible by just “clicking the same view twice very very quickly”. Alternatively, you can just use two fingers and click two (or more) views at the same time, where each view has their own navigation that they would perform. This is especially easy to do when you have a list of items. The above info on multiple click prevention will handle this case.

Edit 4/16/2020: Just in case you’re not terribly interested in reading through that Stack Overflow post above, I’m including my own (Kotlin) solution that I’ve been using for a long time now.

OnSingleClickListener.kt

class OnSingleClickListener : View.OnClickListener {

    private val onClickListener: View.OnClickListener

    constructor(listener: View.OnClickListener) {
        onClickListener = listener
    }

    constructor(listener: (View) -> Unit) {
        onClickListener = View.OnClickListener { listener.invoke(it) }
    }

    override fun onClick(v: View) {
        val currentTimeMillis = System.currentTimeMillis()

        if (currentTimeMillis >= previousClickTimeMillis + DELAY_MILLIS) {
            previousClickTimeMillis = currentTimeMillis
            onClickListener.onClick(v)
        }
    }

    companion object {
        // Tweak this value as you see fit. In my personal testing this
        // seems to be good, but you may want to try on some different
        // devices and make sure you can't produce any crashes.
        private const val DELAY_MILLIS = 200L

        private var previousClickTimeMillis = 0L
    }

}

ViewExt.kt

fun View.setOnSingleClickListener(l: View.OnClickListener) {
    setOnClickListener(OnSingleClickListener(l))
}

fun View.setOnSingleClickListener(l: (View) -> Unit) {
    setOnClickListener(OnSingleClickListener(l))
}

HomeFragment.kt

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)

    settingsButton.setOnSingleClickListener {
        // navigation call here
    }
}
